3. Squarely in front to obtain a flanking fire; in this case, they are found in a small boyau (branch trench) which leaves the principal trench, and it is very difficult to see them from the front.

Thus, in front of La Targette, in studying the position in profile and having moved considerably toward the right for that purpose, I discovered a machine-gun emplacement which completely enfiladed the front of the German trenches for 600 metres.

One generally believes he recognizes a very large number of machine-gun emplacements; but it is infinitely better to mark the position of too many than to overlook one of them; moreover, the Germans have in their defensive organization an unsuspected number of them.

Means of Destroying the Machine Guns.Machine Guns of the Trenches.—In the course of preparation by artillery, a very distinct part of the program is reserved for the destruction of the machine-gun nests. The destruction of the machine guns should not be commenced as soon as they have been located, that is to say, often several days before the final preparations, for the enemy would have ample time to shift them. The 75 is employed to destroy the machine guns. Unfortunately, on account of the dispersion, it does not perfectly fulfil its rôle; its shots often fall to one side and a great number of them are often necessary to find exactly the small space that holds the machine gun.

I recollect that before the attack of May 9, I fretted with impatience and went continually to find the artillery observer, as I saw an accursed rectangular loophole obstinately remain intact up to the end. When we started forward, fire burst out from this loophole, and two sections were wiped out.

To destroy these machine guns, there would be needed not only cannon placed at 1,500 metres, which have many other tasks, but cannon placed in the trench itself. The mountain 80 seems to realize the desired conditions of effectiveness and mobility. Hidden in the trench before the preparation, it unmasks itself during that operation; it takes under direct fire like a rifle all the machine-gun shelters successively, occupying itself with those alone and not leaving them until they are all completely out of action.

Destruction of Machine Guns that may be set up outside the Trenches.—On the 9th of May, the survivors of my company and of the adjoining company, about eighty men, arrived at 11 o’clock[[5]] about 200 metres from the cemetery of Neuville-Saint-Vaast. The cemetery being unoccupied, the field of battle seemed void of Germans. In the distance, the batteries were fleeing. Two machine guns remained in the mill; this was the only resistance over an immense space, but it was sufficient. Impossible for my men to advance; we signal the fact with difficulty to the artillery, which from this time on is under open field conditions; it opens fire a long time afterwards and mistakes the objective. Then before the eyes of our furious men, abandoned by all because they were too far to the front, the cemetery fills up with Germans. Four hours afterwards, the 146th appears on the field and is mowed down by the machine guns; the next day the 229th succeeds it; new repetition with a slight and extremely costly advance.

With these machine guns revealing themselves thus without our being able to foresee their emplacement, and taking up positions to stop our progress in a region no longer familiar to us, we must have the means of suppressing them instantly. The field artillery is too far away; communication hardly exists after passing beyond the extremity of the telephone lines. The question is of the greatest importance and merits study. It would be absolutely necessary that the first waves of attack be followed, after the taking of the first lines of trenches, by light guns, the 37 for example, drawn by their cannoneers. These independent crews would be all eyes and ears to discover the machine guns and destroy them immediately. There are enough officers or noncommissioned officers of artillery to command them intelligently.
